Installation of the HG sprockets

For each sprocket, the surface that has

the group mark should face outward

and be positioned so that the wide

parts of the gear projections on each

sprocket and the A part (where the

groove width is wide) of the freewheel

body are aligned.

• For installation of the HG sprockets, use the special tool (TL-LR15)

to tighten the lock ring.

• To replace the HG sprockets, use the special tool (TL-LR15) and

TL-SR20 to remove the lock ring.

Install the TL-SR20 to the largest sprocket.

The groove is

wide at one

place only.

General Safety Information

WARNING

• Check that the wheels are fastened securely before riding the bicycle. If the wheels are

loose in any way, they may come off the bicycle and serious injury may result.

• If using the CS-6600 (14-25T, 15-25T, 16-27T) in combination with a front chainwheel,

use a double chainwheel. If you use it in combination with a triple chainwheel, gear

shifting performance will drop, and the bicycle may fall over and serious injury may result.

• Obtain and read the service instructions carefully prior to installing the parts. Loose,

worn, or damaged parts may cause injury to the rider.

We strongly recommend only using genuine Shimano replacement parts.

• Read these Technical Service Instructions carefully, and keep them in a safe place for

later reference.

Note

• Do not use the CS-6600 in any combination other than with the CN-7801 / CN-6600.

Other chains cannot be used as the sizes do not match.

• An 11T and a 12T lock ring are available for use with the CS-6600. Use whichever lock

ring matches the sprocket configuration.

• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.

• Do not apply any lubricant to the inside of the hub, otherwise the grease will come out.

• You should periodically wash the sprockets in a neutral detergent and then lubricate them

again. In addition, cleaning the chain with neutral detergent and lubricating it can be a

effective way of extending the useful life of the sprockets and the chain.

• If the chain keeps coming off the sprockets during use, replace the sprockets and the

chain.

• Parts are not guaranteed against natural wear or deterioration resulting from normal use.

• For maximum performance we highly recommend Shimano lubricants and maintenance

products.
